Built to the LSA toolholder style, it accepts LT 16EL inserts secured by a clamp-style holding method, providing rigid, repeatable cutting-edge positioning. The shank measures 0.75 inches wide by 0.75 inches tall and the tool runs 5 inches in overall length. Compatible with inserts carrying a 3\/8-inch inscribed circle, this holder is suited for threading operations where left-hand tool orientation is required by the machine setup or part geometry. Machining professionals and toolroom technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis toolholder is used in external threading applications on metal-cutting lathes in job shops, production machining environments, and maintenance machine shops. The left-hand designation makes it appropriate for operations where the tool must travel away from the chuck or in applications requiring climb-direction thread cutting. The LT series threading platform it belongs to is a dedicated thread-turning system, making this holder appropriate for single-point thread turning rather than milling or grooving operations. No coolant-through capability is present, so flood or mist coolant must be applied externally at the cutting zone.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExternal threading orientation with left-hand holder geometry\u003c\/li\u003e\n  \u003cli\u003eLSA toolholder style with clamp-style insert retention for secure, repeatable seating\u003c\/li\u003e\n  \u003cli\u003eAccepts LT 16EL indexable inserts with a 3\/8-inch inscribed circle\u003c\/li\u003e\n  \u003cli\u003eSquare shank: 0.75 inches wide by 0.75 inches tall for standard toolpost or turret mounting\u003c\/li\u003e\n  \u003cli\u003e5-inch overall length suits standard lathe turret reach requirements\u003c\/li\u003e\n  \u003cli\u003ePart of the KENNAMETAL LT Threading series for dedicated single-point thread turning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with LT 16EL indexable threading inserts.

The machine spindle must be stopped and all motion fully arrested before mounting or adjusting the toolholder in the turret or toolpost. Secure the shank using the appropriate clamping hardware for your turret style and verify insert seating and clamp torque according to the toolholder manufacturer documentation before taking a cut. Confirm tool centerline height relative to the workpiece spindle centerline prior to threading, as centerline deviation directly affects thread form accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: LSA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: LT 16EL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Height\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: LT Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.793 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291800\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1281797\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738288324914,"sku":"1281797","price":212.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a3f21cc33c915484fcb38c607bd276e.jpg?v=1788797742","url":"https:\/\/voomisupply.com\/products\/kennametal-1281797-threading-toolholder-3-4-inch-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
